Arguments about the spread of gender egalitarian values through the population highlight several sources of change. First, structural arguments point to increases in the proportion of women with high education, jobs with good pay, commitment to careers outside the family, and direct interests in gender equality. Second, value shift arguments contend that gender norms change with social and economic development among women and men in diverse positions - traditional and non-traditional alike. Third, diffusion arguments suggest that structural change leads to adoption of new ideas and values supportive of gender equality by non-traditional and innovative groups in society, but that the new ideas later diffuse to other groups through cultural processes. Using the General Social Survey from 1977 to 2006 and comparing the determinants of gender egalitarianism across 86 cohorts born from roughly 1900 through 1985, multilevel models support the diffusion arguments. 相似文献

AbstractThis article covers practical solutions to the problems of cataloging and classifying the majority of “graphic novels” with information on useful RDA changes. The author also discusses analytic serials cataloging, MARC fields, and field types with a list ranked by importance, classification information, and a sample procedure. 相似文献

Forecasts of materials damage from air pollution require (a) knowledge of a “damage function,” (b) an estimate of the exposure of materials to pollutants and other factors that enter into the dose relationship, and (c) the quantity and characteristics of the exposed materials. Uncertainty about any of these factors can lead to unacceptable uncertainty or bias in damage forecasts. Particular attention is given to the influence of the spatial units used to derive forecasts of materials damage. Environmental corrosion can vary significantly over relatively small geographic areas; accordingly, the choice of spatial unit can have an impact on forecasts of damage. The environmental factors that influence materials damage may not be independent over the time of exposure. There appears to be some evidence, for example, that SO2 is not independent of time of wetness, both factors in metal corrosion. 相似文献

As dynamic collaborations between networks of specialists have become more central to developing cutting-edge innovations, designing and sustaining innovation policies that foster them has become an increasingly central concern. This article reviews the characteristics of the “developmental network” or “neo-developmental” states that have been shown to foster innovations at the technological horizon. It then analyzes the US case to suggest why some developmental network approaches to governance have proven relatively durable, while others have not. We conclude with a discussion of what can – and cannot – be learned from the US case, and suggest the importance of comparative work on the sustainability of effective innovation-centered approaches to governance. 相似文献

The estimation of survival rates from analysis of recapture of individually marked animals assumes that all individuals are equally likely to be re-encountered. This assumption is frequently violated in natural populations due to movements to and from the sampling area. We evaluated potential sources of heterogeneity using data from recaptures of 36000 individually marked female lesser snow geese, Anser c. caerulescens , from an expanding population in northern Manitoba, Canada. By stratifying individuals according to marking age and origin (hatched at the colony or not), we assessed the degree to which variation in apparent survival reflected permanent or temporary differences in emigration and effects of handling. In general, for birds ringed as adults, estimated apparent survival rates were significantly lower during the first year after ringing than in subsequent years. By comparing birds ringed as adults (classified by origin) with those ringed as goslings, we were able to demonstrate that these differences are not due to permanent emigration from the colony by transient individuals or heterogeneity of individual capture probability, but more likely reflect differences among individuals in their response to initial marking. Approximately 25% of birds permanently emigrate from the sampling area following marking. 相似文献

The energy use in the residential sector is an important area for compaigns to conserve energy. In the first section of this article, a model is proposed that relates personal, environmental (e.g. home) and behavioral factors to energy use. This model is instrumental in relating variables that determine energy use in the home.In the following these determinants of household energy use: socio-demographic factors, family life-style, energy prices, energy-related behavior, cost-benefit trade offs, effectiveness and responsibility, feedback, information, home characteristics are discussed.In the third section several options for energy-saving campaigns and related research are discussed. 相似文献
